Android TabActivity cannot work properly. bindService Solution

During Android development, we are likely to use TabActivity for development. If your program needs to bind a Service to each Activity in TabHost of TabActivity, we usually perform the bind operation in the onCreate () method of the Activity corresponding to the Tab page. However, the practice shows that this method cannot achieve the binding effect. I checked it online, this vulnerability was found in Google Android Issue. Detailed defects are found here (Google Android Issue 2483). oliver on the third floor provides a positive solution.

Using getApplicationContext (). bindService instead of just bindService on your activity solves

The problem as it is using the higher level application context.

That is, if bindService is required for the Activity in TabHost of TabActivy, you need to call getApplicationContext () to obtain the Context Environment of the Activity to be normal bindService, that is, in onCreate () use this. getApplicationContext (). bindService ([args…]) Otherwise, bindService will always fail and return false.
